| Description | NETSHIELD is an anti-virus NLM (NetWare Loadable Module)
for Novell NetWare/386 Version 3.11. It checks network file
servers for both known and unknown viruses. Known virus
detection, including stealth and polymorphic (mutation engine)
viruses, is done using McAfee Associates' VIRUSCAN virus
scanning technology. Unknown virus detection is handled by
computing two 16-bit Cyclic Redundancy Checks (CRC) against
files and then periodically comparing the file against its
CRC for changes. |
